Release new Locust version

[heyman]

I think it's time we do a real release of 0.8 so that people can actually get the latest version (with Python 3 support) when they run pip install locustio.

I'd like to get #656 and #549 merged as soon as possible and I propose that we do one of the following three things:

1. Merge both Remove --num-requests/-n in favor of --run-time/-t #656 and Refactored stats code and display median as well as 95% percentile response times in web UI's charts #549 and then release 0.8 (YOLO)
2. Merge both Remove --num-requests/-n in favor of --run-time/-t #656 and Refactored stats code and display median as well as 95% percentile response times in web UI's charts #549, release a 0.8rc5, wait a week, and then release 0.8.
3. Release the current master as 0.8, then merge Remove --num-requests/-n in favor of --run-time/-t #656 and Refactored stats code and display median as well as 95% percentile response times in web UI's charts #549 and immediately release a 0.9rc1.

What do you think?

I'd be in favor of releasing current master as 0.8 now and building a RC for those other PRs.

Mainly because #656 will potentially be a big change for how people are using Locust with --no-web and it'd be nice to put that into another RC (there were a lot of changes in 0.8 too).

Plus, not really a big deal to have lots of releases in my opinion. I'm almost always a fan of more releases vs larger ones when digital space is involved, too, makes it easier to identify any regressions :)

Ok, that sounds good to me! I'll go ahead and make a release of 0.8 now then.

0.8 has been released!
